From the start of the 2021 season, this racer will be campaigned in the Porsche Mobil 1 Supercup as well as the national Porsche Carrera Cups in Germany, France, Asia and Benelux and for the first time in North America. The spectacularly styled Cup car is the first racing version based on the current 992 generation and the first makes-cup racer of the sports car manufacturer to feature a wide turbo-spec body. Producing around 375 kW (510 hp), it exceeds the output of its immediate predecessor by 25 horsepower. Moreover, the new GT3 Cup can run on synthetic fuels, which significantly lowers CO2 emissions under racing conditions. The lap times of the completely new Cup 911 should be slashed by a good one per cent, depending on the track layout. Delivery to teams will begin in February 2021.

Porsche presented the very first 911 Cup car in 1990. It was based on the 964 generation and headed into its debut season in the German Porsche Carrera Cup with 260 hp. From 1993, it was also raced in the newly established Porsche Supercup, which ran as part of the Formula 1 support programme. Over the next years, five more generations of this exceptionally successful racing vehicle followed - of which to date a record number of 4,251 units have been produced.

"The 911 made history as the baseline model for the Carrera Cups and the Porsche Mobil 1 Supercup - no other racing car has found as many satisfied customers since 1990 as the 911," states Michael Dreiser, Director Sales Porsche Motorsport. "The new 911 GT3 Cup now starts a new chapter. Our goal is to pass the 5,000 mark in production over the coming years. Like its ancestral lineage, this model will also assist a whole new generation of talented racing drivers on their path to professional motorsport and shape the face of our customer sport commitment around the world."

The groundwork for the latest model was laid in 2018. Concrete development began in early 2019. The main development goals of the team led by project manager Jan Feldmann were to further improve performance, achieve a more aggressive design, easier handling and greater durability with less outlay in terms of time and maintenance. The result is reflected in many aspects of the new racing vehicle, which, like its predecessor, rolls off the production line in Stuttgart-Zuffenhausen alongside the 911 production models. 

One of the most striking features of the new 911 GT3 Cup is its optimised aerodynamics and the overall more muscular appearance - it looks even more impressive at first glance. This is partly thanks to the wide turbo-spec lightweight body that is being used for the first time in the Cup car. Measuring a total of 1,902 millimetres in width, it exceeds the rear width of the previous model by 28 millimetres and is distinguished by its additional cooling air inlets in front of the wheels. Furthermore, the front axle of the 992 generation of the 911 is also significantly broader. Thanks to additional flared fenders, the new 911 GT3 Cup now measures as much as 1,920 millimetres at the front axle. This opens the door for a harmonious wheel-tyre combination with 12-inch wide rims on the front and 13-inch wheels at the rear axle. This is typical for GT racing and has a positive effect on the handling and driveability of the racing car.

At the same time, the seventh generation of the Cup racer generates noticeably more aerodynamic downforce. This is thanks to the combination of the rear spoiler with the larger rear wing and front apron, which was specifically adapted to racing by means of a front lip spoiler and strategically-positioned separation edges. The eleven-stage adjustable rear wing with a ‘swan neck' mounting ensures uninterrupted under-wing airflow. This improved aerodynamic efficiency also ensures more stable handling, especially in fast corners.

The body of the 991.2 generation Cup car consisted of 70 per cent steel and 30 per cent aluminium. The ratio in the successor has been switched. The fact that the vehicle still weighs around 35 kilograms more with a dry weight of 1,260 kilograms is due, for example, to extra struts being added to the steel safety cell. The removable escape hatch in the roof complies with the latest FIA standards. All windows in the GT3 Cup are made of lightweight polycarbonate and have scratch-resistant hard-coat glazing. The doors, engine hood and rear wing are made of carbon-fibre reinforced plastic. In contrast, the front hood with its distinctive exit-air duct and central air intake is a prime example of the intelligent use of materials: Like in the 911 Carrera, it is made of aluminium - which lowers repair costs in the case of an accident.
